Abstract: PROBLEM TO BE SOLVED: To provide a solid state image pickup device capable of reducing its size and cost by reducing the number of processes for assembling and adjusting work and the number of parts for peripheral units (a packaging base, a connection member, etc.), and a prism unit to be used for the device. SOLUTION: A solid state image pickup element unit 7 in the prism unit is constituted so that three solid state image pickup element chips are integrated and arranged in parallel so as to be stuck close to a color separation prism(CSP). The CSP is constituted so that prescribed beams 5, 6 color-separated by dichroic mirrors 2, 3 are fully reflected by using respective reflection parts 9, 10 to emit the reflected beams from an outgoing face practically in the vertical direction. Since the optical path length of a beam 4 is different from that of other beams 5, 6, a convex lens 8 is arranged on the optical path so that the appearing images of respective beams 4 to 6 obtained by the color separation of a beam 1 can be made incident upon the same plane of the unit 7.

Filed: 1989-06-08
Abstract: PURPOSE:To realize a linear motor driven elevator with highly reliable braking action by providing an elevating body with a brake and erecting a damping conditional body pressed by the damping piece of the brake in addition to the guide rail of the elevating body. CONSTITUTION:An electromagnet 9d is magnetized simultaneously with the energization of a linear motor, and a lever 9b is sucked against the pressing of an energizing body 9e to separate a damping piece 9c from a damping conditional body 10. When a first elevating body approaches an elevator stop provided at an elevating path, a linear motor is de-energized. As the electromagnet 9d is demagnetized when the first elevating body reaches the appropriate place of the elevator stop, the damping piece 9c is pressed to the damping conditional body so as to brake a second elevating body 4, thus stopping the first elevating body. The braking action by this brake 9 is generated by the friction between the damping piece 9c and the unoiled damping conditional body 10. The stable damping characteristic can be easily obtained as well as damping action with high operating reliability can be acquired.
